Sodium chromate

Understanding Sodium Chromate:


Sodium Chromate is a chemical compound with the sodium chromate formula Na2CrO4. It is a yellow crystalline solid, commonly found in the form of beads and pellets. The compound is highly soluble in water, creating a yellow solution.


Let's explore some key properties of Sodium Chromate:


  • Chemical Composition:

Sodium Chromate consists of sodium ions (Na+) and chromate ions (CrO4^2-).

The balanced chemical equation for the formation of Sodium Chromate is: 2NaOH + CrO3 → Na2CrO4 + H2O.


  • Physical Appearance:

Sodium Chromate is a bright yellow solid, which is indicative of its chromate ions.

It is available in different forms, including beads and pellets, providing flexibility in various applications.


  • Solubility:

Sodium Chromate is highly soluble in water, forming a yellow solution.

This solubility makes it suitable for various industrial processes and applications.


  • Packing and Storage:

At Desicca Chemical Pvt Ltd, we understand the importance of proper packaging. Our Sodium Chromate is available in:

  • Local packaging: 50kg HDPE Bag with Airtight inside polyliner.

  • Export packaging: 50kg fibre drums.

These packaging options ensure the quality and integrity of the product during transportation and storage.
